Constructor Detail

### Kangaroo.KangarooTwelve

    public Kangaroo.KangarooTwelve()

  Constructor.

### Kangaroo.KangarooTwelve

    public Kangaroo.KangarooTwelve(int pLength,
                                   CryptoServicePurpose purpose)

  Constructor.

Parameters:
  `pLength` - the digest length

### Kangaroo.KangarooTwelve

    public Kangaroo.KangarooTwelve(CryptoServicePurpose purpose)

Method Detail

### getAlgorithmName

    public java.lang.String getAlgorithmName()

  Description copied from interface: `Digest`
  return the algorithm name

  Returns:
    the algorithm name

### getByteLength

    public int getByteLength()

  Description copied from interface: `ExtendedDigest`
  Return the size in bytes of the internal buffer the digest applies it's compression function to.

  Specified by:
    `getByteLength` in interface `ExtendedDigest`
  Returns:
    byte length of the digests internal buffer.

### getDigestSize

    public int getDigestSize()

  Description copied from interface: `Digest`
  return the size, in bytes, of the digest produced by this message digest.

  Specified by:
    `getDigestSize` in interface `Digest`
  Returns:
    the size, in bytes, of the digest produced by this message digest.

### init

    public void init(Kangaroo.KangarooParameters pParams)

  Initialise the digest.

  Parameters:
    `pParams` - the parameters

### update

    public void update(byte pIn)

  Description copied from interface: `Digest`
  update the message digest with a single byte.

  Specified by:
    `update` in interface `Digest`
  Parameters:
    `pIn` - the input byte to be entered.

### update

    public void update(byte[] pIn,
                       int pInOff,
                       int pLen)

  Description copied from interface: `Digest`
  update the message digest with a block of bytes.

  Specified by:
    `update` in interface `Digest`
  Parameters:
    `pIn` - the byte array containing the data.
    `pInOff` - the offset into the byte array where the data starts.
    `pLen` - the length of the data.

### doFinal

    public int doFinal(byte[] pOut,
                       int pOutOffset)

  Description copied from interface: `Digest`
  close the digest, producing the final digest value. The doFinal call leaves the digest reset.

  Specified by:
    `doFinal` in interface `Digest`
  Parameters:
    `pOut` - the array the digest is to be copied into.
    `pOutOffset` - the offset into the out array the digest is to start at.

### doFinal

    public int doFinal(byte[] pOut,
                       int pOutOffset,
                       int pOutLen)

  Description copied from interface: `Xof`
  Output the results of the final calculation for this digest to outLen number of bytes.

  Specified by:
    `doFinal` in interface `Xof`
  Parameters:
    `pOut` - output array to write the output bytes to.
    `pOutOffset` - offset to start writing the bytes at.
    `pOutLen` - the number of output bytes requested.
  Returns:
    the number of bytes written

### doOutput

    public int doOutput(byte[] pOut,
                        int pOutOffset,
                        int pOutLen)

  Description copied from interface: `Xof`
  Start outputting the results of the final calculation for this digest. Unlike doFinal, this method will continue producing output until the Xof is explicitly reset, or signals otherwise.

  Specified by:
    `doOutput` in interface `Xof`
  Parameters:
    `pOut` - output array to write the output bytes to.
    `pOutOffset` - offset to start writing the bytes at.
    `pOutLen` - the number of output bytes requested.
  Returns:
    the number of bytes written

### reset

    public void reset()

  Description copied from interface: `Digest`
  reset the digest back to it's initial state.

  Specified by:
    `reset` in interface `Digest`
